If a Firestone sump pump is losing ground, start by cutting its power safely, checking the float and clearing the outdoor end of the discharge. Most failures trace to a stuck switch, a worn check valve, a tripped circuit or a motor that has given out. Call the number on this page to be connected with a local plumber in Firestone.
Firestone at a glance
Firestone is a fast-growing Weld County town along I-25, mostly newer family subdivisions, so the typical pit here was installed by a builder and may hold a basic pump that has never been tested. Sewer comes from St. Vrain Sanitation District, which says the building sewer line belongs to the property, not the district. Sump water should never be sent into that line; it belongs outside on ground that drains away from the house. The district staffs a 24-hour line for sewer backups at (303) 776-9570.
What to do right now
- Cut power at the breaker if water is close to the outlet.
- Check the float. Builder installs sometimes leave the cord where it can snag the float.
- Clear the outdoor end. Snow, ice, landscaping rock or a buried pop-up emitter can block flow.
- Run a cycle and listen. Water rushing back into the pit after shutoff means a bad check valve.
- Lift belongings off the basement floor.
- Call a plumber if the pump hums, overheats or will not run.
Signs and likely causes
| Symptom | Likely cause |
|---|---|
| Water in the pit, no sound | Stuck float, failed switch or no power |
| Hums but nothing leaves the pipe | Clogged intake, jammed impeller or frozen discharge |
| Runs in short bursts | Float set too tight or check valve leaking |
| Runs on dry days | Water returning down the pipe, or a supply leak |
| Wet ground by the foundation | Discharge too short or aimed back at the house |
What affects the cost
- Repairing one part versus replacing the pump
- Upgrading a builder-grade pump
- Rerouting or extending the discharge line
- Battery backup and high-water alarm
- A backflow preventer permit if you add a water-powered backup
- Freeze protection where the line crosses a long, exposed yard
Firestone has run a backflow prevention and cross-connection program since 2019, and the Building Division's fee schedule lists residential backflow preventer permits, so a water-powered backup is not a casual add-on. Most homes are on Town of Firestone water, while Barefoot Lakes is served by Little Thompson Water District, so check which one serves you. The Firestone Building Division can confirm what your pump job needs.
